I always approach film as a fan.

As an audience member and as an actor I much prefer to find ambiguity.

We did a lot of that in drama school: intellectualising and maybe justifying your position. 'I am a thinking actor and I have thought this through' - well, just do it. I much prefer the doing aspect.

Even if I'm playing a superhero, it has to be steeped in reality.

What I find really interesting is to try and mix it up, to push myself and try different things. I don't want to stay in my comfort zone. I want to take risks and keep myself scared.

If you're dealing with heavy topic matter, sometimes it's good to have a lightness going into it because it allows you to be open to possibilities, rather than getting rigidly stuck into a certain mind-set. People are strange. When you break up, sometimes you end up laughing with one another, as opposed to crying. Things in life are unusual, and to find those things, it's best to be relaxed.

I just went off for two months traveling around Europe on a motorcycle and pretty much turned my phone off. I did 5,000 miles with my dad. We went through Holland, Germany, Austria, Slovenia, Croatia, Bosnia, Montenegro, Italy... and then I did Spain and France by myself.
